AUTOMATIC PHOTOGRAPHIC-FILM-SPOOL-MAKING MACHINE.

Application filed April 4, 1925. Serial No. 20,723.

This invention relates to machines for automatically making all metalspools particularly adapted for spooling photographic film. One objectof our invention is to make a machine which will assemble the spool coreand flanges together without attention from an operator. .Another objectis to provide a machine which will assemble the flanges and coretogether with a definite W relation to each other so that a slot in aflange will always bear a definite relation to a slot in the core to.facilitate the spooling operations. Another object is to provide amachine in which the flanges are spot welded upon the core. Anotherobject is to provide a machine in which the flanges so attached will bedefinitely spaced one from the other. Another object of our invention isto provide a machine in which the strength of the welded flanges aretested, and the defective spools are discarded. Another object of ourinvention is to automatically remove the defective spobls from themachine. 'Another object is to automatically identify all spoolsdefective because of improper dimensions or defective welding andseparate .these spools from the good spools. Another object is toprovide a machine with an upsetting mechanism-adapted to size spoolswhich have been previously Welded together, and other objects willappear from the following specification, the novel fea-' turesbeingpointed out in the claims at the end thereof. In making spools forcarrying photographic film it is necessary for best results toprovideflanges which are parallel, which have square corners with the flange towhich they are attached, which have the-periphcries concentric, andwhich have a firm connection with the core so that they can not bereadily displaced therefrom. The film and film backing paper to runsmoothly on the core between the flanges must have a smooth surface tocontact with, and onethat is free from protuberances or indentationsexcept forthe slot through which the end of the lead strip may pass inthreading the film to a take-up spool in the camera. With our machinewehave provided -means for adjusting the machines so that spools withthe allowable or desired tolerances may be automatically made andseparated from-spools which are defective in Fig. 1 is a side elevationof a machine constructed in accordance with and illustrating oneembodiment of our invention, certain parts being omitted for clearness;

Fig. 42 is a timing chart illustrating the relative movements of thecams, rotors and I from a loading and righting station A to a flangeapplying station B, after which the spool is carried to an upsetting orsizing station C. The spool is then carried to station D where a secondrotor 2. picks the spool from rotor 1 and carries it to station E whenthe spool is tested for the strength of the weld. From station E it ismoved to station F where the spool is sized and sorted. The spool corefeeding mechanism 1s designated broadly as H, the core rightingmechanism as J, the flange feeding mechanism as K, the spot weldingmechanism as L, the-upsetting mechanism as M, the testing mechanism asN, and the sorting mechanism as O.

The main rotor 1 is intermittently actuated from a power driven shaft 3through gears 4 and 5, the latter driving shaft 6 upon which there islocated a Geneva driver 7, the roller 8 of which is positioned to drivetwo Geneva star wheels 9 and 10, and by per mitting the roller a; enterthe Geneva slots 11 and 12 at an angle, a dwell is obtained between themovement of the two Genevas. Geneva 10 throughshaft 13, gears 14 and 15and shaft 16 moves the main rotor 1. (See Figs. 1 and 2.)

' R otor 1 consists of a pair of spaced plates 1 and 1' having notches17'spaced about its periphery at Geneva 10 moves the rotor a quarter ofa complete revolution each time it is actuated by the driving member.The second rotor 2 also consists of pairs of spaced plates 2 and 2'which are spaced to extend out idev of the main rotor plates 1 and 1.The second rotor' is actuated Geneva star wheel 9 which, as shown 1ncolumns Y'and II of the time chart (Fig. 42) drives the rotors atdifferent time intervals with a short period of rest (here shown as 10)between the movement of the two rotors. The second rotor is called thetransfer rotor.

' The various stations and the functions performed at thestations willnow be described.

Station A, the core supplying station preferably comprises a core supplychamber 18, as best shown in Fig. 3. This supports shafts 1'8, androllers 19 over which an end- A roller 19 isdriven through pulley 22,belt 23 and pulley 24' which derives power in a manner to be hereinafterdescribed. In Fig. 1 a modified core supply station is shown, this beingar-. ranged so as to he as close as possible to the flange loadinghoppers to be hereinafter dcscr 1bed. In Flg. 3 the only difference isin the position of the hopper 18. The spool cores, as shown in Fig. 4are preferably metallic cylinders 24 having a slot 25 in one side. Theseare fed by the belt into a chute 26 and when a pair of notches 17 aremoved beneath chute 26, the lowermost core willriphery 27' of the rotorwheels.

main upright frame members brackets 38.

The holding finger 27 is one end of a bell crank 31 pivoted at 32 to arotor disc It op erating in a cut-out 33 in the disc.

The other end 34 carries a roller 35 lying in the cam slot 36 of cam 37.A hoiding fin ger and cam are provided for each disc 1 and 1, and, asbest shown in Fig. 2, earns 37, do not move with shaft 16 but areaffixed to the through 7 Nov. 3, .1925. v

To right the core, that is to bring the slot in the desired "position weuse the mechanism designated broadly as J shown in Figs. 5 to 7inclusive. We provide a shaft 39 mounted in'a bearing 40 which iscarried by the frame member 41. This shaft may both turn'and slide inbearing 40. The end of the shaft is hollowed out at' 42 and a spring 43is mounted "therein adapted, to press a curved blade 44 through a slot45 in the shaft. This blade forms a latch adapted to engage the spoolslot 25 when the shaft 39 enters the core, but the shape is such that itmay readily snap into and out of the slot.

Shaft 39 is revolved by the following clutch mechanism: a spool 46 ispinned to shaft 39 and carries a face 47 adapted to contact with theleather clutch face48 of pulley 49. Pulley 49 isanounted on sleeve 40and is free to turn thereon, but when shaft 39 is moved to the right,Fig. 7 the clutch is made and the shaft and pulley revolve together.

As shaft 39 revolves blade 44 snaps into slot 25 and turns core 24turning it until detent 50 actuated by spring 51 snaps into thev slot25, at which time blade 44 snaps out and the spool core is properlypositioned. When .shaft 39 is moving into the core, the thrust on thecore is taken up by the bracket 52, Figs. 2 and 7, and when drawn fromthe core the pull is taken up by detent 50, which as shown in Fig. 5,lies in the extreme end of slot 25. Thus'the core is not displacedduring the righting operation.

Shaft 39 is moved back and forth in the timed relation indicated incolumn III of the time chart, by the rock shaft 54. This shaft supportedby brackets 55 carries an arm- 56, best shown in Fig. 16, which carriesa yoke 57 embracing the slot 58 of spool 46. Shaft 54 carries a pinion59 meshing with a rack 60 on arm 61, which, as best shown in Fig. 13,.ismoved through a cam 62 on the power driven shaft 63. This shaft throughbevel gears 64 and 65 is driven from shaft 6 (Fig. 1). Cam 62 has a slot67 in which roller 68 of lever 69 moves. This lever 18 pivoted at 7 0 toone end of a bell crank lever- 71 pivoted at 72 to bracket 73 andcarrying on the other end a pin 74 supporting a spring 75, the other endof which is attached to stud 76 of arm 61.

The core 24, properly positioned is now moved to station B to receiveflanges from mechanism K and have them welded in place by mechanism L.

The flanges for each end of the core are fed by the same mechanism K, sothat belng similar, only one will be described in detail. The flanges 77and 78 (Fig. 41) preferably differ in that flange 77 is provided with aslot-79 in the central part of which 80 is an aperture, whereas flange.78 is preferably provided with a central aperture only as at 81. ifdesired, however, the flanges may be exactly the same. We also prefer toform the edges of the slot and aperture inwardl so as to forma flange 82since this forms a guiding flange for positioning the slot properly inour machine, and has certain advantages when used in the roll filmcameras now on the market.

The flanges 77 are placed in a hopper 83 (Figs. 1 8 and 10) and in thishopper 1s a disc 84 carried by shaft 85 operated through gears 86' and87 from shaft 88. Shaft 88 through sprockets 89 and 90 and chain 91 isoperated from power shaft 63. The two hopper discs may be' driventogether by means of sprockets 92 and 92' which are connected togetherby chain 93, as indicated inbroken lines Fig. 10.

' Disc 84 is turned agitating flanges 77 and causing them to slide downchute 94 in {which there is a groove 94 which (Fig. 9) holds the slotflanges 79 in a fixed position. At the bottom of chute 94 are a pair offlange gripping spring arms 95 which position the flange while thebottom of the flange rests on the lug 96.

The flanges are each applied to the spools by means of slidingelectrodes 97. One electrode has a pilot 98 to which there are attachedflanges 98' which hold the flange slot 7-9 in the desired position. Theother electrode has a, pilot 98 which .enters the cen tral aperture 80.These electrodes are shown in Figs. 12 and 12 As this electrode 97slides to, the right, Fig. 12, the. flange is moved from its holdingspring arms 95 from the position showh in full lines to the positionshown in broken lines, in which it lies against the core 24 in positionvfor welding. The welding mechanism L includes the electrodes 97 as abovedescribed, and the following mechanism. Electrode 97 (each side is thesame) slides in a sleeve 97' insulated by sleeve 99 from frame 100.Member 97 is actuated from the rock shaft 54 which is fully described asthe operating means for the righting mechanism J. The electrode on theopposite side is moved through arm 61 (Fig. 13) rack 101,- gear 102,shaft 103 and an arm 104. There is an arm 104 on each side of themachine. I Arm 104 has a yoke 105 (Fig. 16) embracing the slot 106 inspool 107. Thisspool has a slot 108 adapted to slide about a pin 109carried by electrode 97. Spool 107 has a flange surrounding a part ofspring 109 which presses the spool from the stop 110 attached toelectrode 97 by a screw 111, this also forming the connecting member forthe electric cable 112. A guide rod 113 insulated at 114 from member 110by sliding in hearing 115 prevents electrode 97 from turning. As willreadily be seen the spool moves the electrode against the flange andinto its Weldin position in which it is resiliently v pressed by spring109 until released by the rock shaft. The timed relatior of this move;

.Fig. 18, the power is derived from theline wires 122 and 123 from onewire of which a Wire 124 leads to brushes 125 and 126 and thence throughwire 127 to rheostat 128 which is tapped off different coils of theprimary 129 of the transformer 7, wire 129 leading back to wire 123.

i '4 The secondary transformer coil 130 has ing 143 by link 144androcker arm 145 piv- 'oted at 146'to the frame and having a roller 147engaging the slot 148 of cam 149 on power shaft 63. The other wire 133leads from the secondary through brushes 134 and 135 and Wire 136 to oneelectrode 79. The other electrode is connected to the secondary coilthrough wire 137 brushes 138 and 139 and wire, 140.

The switch hub 118 turns freely upon a shaft 150, (Fig. 22) which ispower driven through gears 151, 152 aiid 153 the last mentioned gearbeing mounted on the power shaft 3. Gear 152 is carried by an adustablearm 154 and by selecting a gear 0 the desired size the speed of shaft150 may be altered at will. A clutch face 155 is carried by disc 156pinned to shaft 150 and this face 155 contacts with disc 157 carried bydpins 158 spring pressed by springs 159 tower the clutch face.

Disc 157 turns freel upon shaft 150 and is notched at 160 to orm a stop.A latch 161 (Figs. 20 and 21) pinned to shaft 162 is adapted to contactwith the sto and'may be actuated through link 163 an lever 164 pinned toshaft 165 and held by spring 166 im the direction indicated by thearrows, Shaft 165'carries a tri 167 in the path of the striker 168 whichis a justably carried on an arm 169 having a slot 170 and boltconnection at 171 with the Geneva driver 7. The roller 168 may be movedwith respect to the roller 8 of the Geneva driver 7. At each revolutionof roller 168 the trip is actuated latch 161 causes disc 157 to come toa stop.

The location of the rotary switch is shown in Fig. 19.

It should be noted here that there are three main adjustments for thespot welding operation. First the voltage and amperage of the weldingcurrent may be varied by the rheostat, that is the taps on the primarytransformer coil. Second the duration of the welding is controlled bychanging the speed of the commutatoror rotary switch. Third, the time atwhich the welding'current is applied relative to the other functions ofthe machine may be varied by the. adjustable trip (170-171) for therotary switch; Of course, these adjustments are not necessarily alteredafter once made, but are desirable so that the welding conditions may bealtered to take care of different metals from which the spools may bemade and different welding requirements. One advantage is that ifdesired the welding may be adjusted to heat the flange and spool to suchan extent that the. next operation, the upsetting mechanism M may beperformed while the metal is still hot. \Ve do not limit ourselves oreven prefer to upset'the flanges in a heated condition as the advantagesderived from such treatment depend chiefly upon the metal used. WVit-h.some 'metals the sizing can be done to advantage when the metal is in anunheated condition.

tain the desired resiliency.

From station B the welded spool is moved to station C where the fihnspool is upset, or sized. This is accomplished by the mechanism M, shownin Figs. 23 to 25 inclusive. As the spools formed in the machine havethe flanges spaced by blocks of fixed length (143 and 141) the naturaltendency in case of inaccurate welding is for the spool flanges to bespaced too far apart. To overcome this we upset the flanges to drivethem to gether. Power shaft 3 is provided with a pair of cams 175 whichare engaged by bearings 176 on arms 17 7 which are pivoted at 178 toarms 17 9 slidable in bearings 180. These arms are pivoted at 181 .tolinks 182 attached to pivots 183 joining links 184 and 185 which formtoggles. Links 184 are pivoted to housings 184 and links 185 are pivotedto ears 186 from slides 187 movable in the ways 188. Bolts 189 and nuts190 form an adjustment for the plungers 191 .which terminate in heads192. At each revolution of shaft 3 the heads strike the ends of theflanges driving them inwardly if they should happen to be separated toogreat a distance due to defective welding.

After the sizing operation the spool is moved to station D, where it istransferred to the transfer rotor 2 in the following man ner: referringto Figs; 31 and 32, the rotor 2 turns upon shaft 191 to which is afixed'Geneva gear 9. Each disc 2 and 2 is provided with spool holders spaced90 about their peripheries, a detail being shown in Fig. 30. As hereshown a centering pin 192 is mounted on the end of a shaft 193 movableby means of a spool 194 through a rocker arm 195, shown inFigs. 31 and32. Shaft 193 has a pair of notches 196.and 197 having inclined walls,and with which; a pointed plunger 198 cooperates. This"- plunger ispressed by a strong spring 199 toward the notches, for a purpose to behereinafter described. v

The spools 194 may be moved by the rocker arm 195, which is pivoted at196- to one side of shaft 191. hen the upper spbol (Fig. 32) is movedin, the lower one is moved out so that-a spool is graspedat station D asa spool is released from station F.

Each arm 195 has an extension 197* from their pivots 196 and these armsare pivoted at 197 to rods 197 which extend down (Fig. 2) being attachedto hell crank levers 200 i v oted at 201 to brackets 201 and actuatetogether by rod 202. Rod 203 may be moved by bell crank lever 204 towhich it is pivoted at 203, this lever being fulcrumed at 205 and havingan arm attached at 206 to arm 207. Arm 207 carries a roller 208 engagingcam slot 209 (Fig. 1) of cam 210. on shaft 211 operated through bevelgears 212 and 65. Thus the rocker arms 195 move together.

Since the ends- 213 of the rocker arms are elongated they slide to andfrom the spools 194 as the rotor 2 turns. The rocker arms, being pivotedto the frame of course remain in the same location, therefore the spoolsmove to and from the ends 213 as the rotor moves. plunger 198 snaps intoeither of the notches 196 or 197. At station D the pins 192 are movedinto the spool positioned between them by the main rotor 1.

The transfer rotor 2 then moves the spool to station E where the flangesare tested for strength. If improperly welded a flange is pulled off andthe spool is discarded. To accomplish this the following mechanism isused: on table 215 (Fig. 1) forming part of the frame there is mounted aslide 216 (Figs. 26 to 30 inclusive) this slide moving on the dovetailtrack 217 and carrying a yoke 218 extending downwardly therefrom. A link219 (Fig. 8) is pivoted to the yoke at 220 and is; moved by an arm 221pivoted at 222 to the link, at 223" to the frame and at 224 to a rod 226moved through lever 225 on shaft 226 and having a roller 227 engaging acam slot 228 of cam 229 on shaft 63. Column VII of the timing chartindicates this move- I ment.

Attached to slide 216 is a spool gripper 229 consisting of jaws 230having a snap latch which may comprise a rounded plunger 231 pressed byspring 232 into the jaws so as to just hold a spool core 24 in place. Oneach side of table "215 (Fig. 28) are brackets 233 supporting strippingrods 234 which pass freely through apertures 235 when the slide movesthe spool gripper 229. Apertures'235 are in the form of slots permittingthe breaking blocks 235' to move.

Also attached to slide 216 is anair cylinder 230' equipped with 'a'piston head 231 and piston 232. This piston is held nor- 1 plate 238attached at 239 to the wedge has downwardly -formed ends extending intoslots 240 in the breaking blocks to move them from-as well as towardeach other when the piston moves.

In Fig. 33 there is a detail of the air valve used with cylinder 230'."This valve includes a body portion 241 in which the valve slide 242 islocated, this being shaped like a one on each side a bearing 250 ofbrackets 251 through which the rod may slide; Thisv brackethas a bearing252 which may be adjusted by set screw 253 upon a rod254 attached tobracket 255 (Fig. 1) affixed to the main frame. Obviously when slide 216moves toward the spool, rod 247 will move also until stopped by 249strikin bracket at which time air enters the cy inder and separates thebreakers. The air pressure is set to any desired pressure, and is suchthat a defeotive'weld will be detected by the flange separating from thecore.

-When the slide 216 moves from the rotor 2 s ring 246 will move rod 247so that the sli e valve 242 will uncover vent 256 permitting air toescape about the reduced portion 243 and out through vent 257, since thespring 246 is stronger than the air pressure opposing it. Stop 248 bystriking bracket 251 forms a supplementary valve trip in case spring 246fails to function. This also cuts off the airinlet 244 as portion 258 ofthe valve lies directly over this opening.

If the spool is found perfect and the flanges suflic'iently Welded jaws230merely snap from thespool and it is retained on the pins of rotor 2.But if the flanges are de- 4 fective the spool pins will be removed. If

either or both flanges break the breakers 235 spread outwardly (impelledby wedge 234 and piston 232) so that they strike the ends 260 of shafts193 (Fig. 30) thereby thrusting out on the shafts moving them from'theposition shown at P to that shown at Q and,

since the distance a from the end to the notch is thus moved back tofrom a to b the point 198 of the plunger will be brought. onto theinclined wall of notch 197 and spring 199 will .then, in seating plunger198 in notch 197 move shaft 193 to positionindicated at c,'in which theend 260 of the shaft 193 will lie at K. Then, the spool centering pins192 having-been withdrawn the jaws will draw the spool back with it andit may then be stripped b the stripper rods 234 after which it may fa 1.past the baflie plate 261 (Fig.

' 34) so as to'roll down chute 262 into the discard box 263. v

" It must beremembered that the rocker arms function only at stations Dand F to actuate the spool centeringE pins and the breakeris located atstation If the spool has been defectivethe spool centering pins aremoved out at station E. Consequently the spools can not move fromstation E to station F i and slide onto the the spools from station 'Ein their normal or spool holding position, because in the vast majorityof casesthe spools will be perfect and are therefore retained on thecenterlng pins. 192. )Ve therefore provide normalizing cams 275 whichlie in the paths of spools 194 and are adapted to strike the curvededges 276 (see Fig. 30) and move the spools inwardly so. that the pins192 will reach their spool holding position before reaching station F.Therefore the centering pins and spools come to station F in theirnormal spool holding position regardless of whether or not the breakerfunctions at station E.

When the spool reaches station E it has been completed and tested, andat this station it is tested for length and sorted, the spools notcoming within the desired limits of accuracy being separated from theusable spools.

Refcrrin to Figs. 34 to 40 inclusive the sizing mec ianism 0 consists ofthe following mechanism. A sorter ejector arm 280 is carried by shaft281 to which is also attached a-rm 282 which is pivoted to a link 283.'This link is pivoted at 284 to a bell crank lever 285- which turnsfreely upon shaft 226' and has a-pivotal connection at 286 with link 287which carries a pin 288' extending through roller 147 which engages slot148 of cam 149 (see Fig. 8). The timing chart in column XIV indicatesthe movement of the sorter ejector arm.

Figs. 38 to 40 inclusive show details of the sorter ejector arm 280which includes a hook 290 with a'detent 291. This preferably consists ofa rod pressed by spring 292 into past the test block 299 which consistsof a frame 300 mounted to turn with shaft 301 and having arms 302. Oneof these arms has a pad- 303, and the other has a pad 304 normally heldtowards 303 by'spring 305, this movement being limited by nuts 306" and307. Pads 304 and 303 are carefully adjusted as to the distance betweenthem so that a normal spool just passes between these pads, if, however,the spool is too long it will engage the pads and swing the frame 300andwith it shaft301.

Shaft 301 carries a bell crank lever 308,

one arm of which 309 is pivoted to a rod i from the pins the ejector armcarries it down drawer 310 carrying a weight 311, the other arm rockedthe following mechanism is used., One arm 302 carries a latch 320pivoted at.

321 and having an arm 322 held by spring 323 against lug 324. Theejector arm shaft 281 terminates at 325, and there is pinned on this endaslideway 326. This slideway turns-- with the arm 280. 'There is a latch32'? slidable through the slidewayand carrying a roller 328 movable inthe cam track 329 so that as arm 280 moves. the latch followssubstantially the path indicated by the dot and dash line Fig. 35, sothat it Wlll engage latch 320 and move frame 300 up to its full lineposition (Fig. 34) at which time it will slip oil.

Thus it will be seen that all perfect spools pass between pads 303 and304 without rocking the baflie so the spools drop into drawer 319,whereas, if too wide the pads will be engaged and the bafie'ro'cked.This cares I for all spools since the upsetting station with the sizeblock precludes the possibility of any spoolsbeing too narrow.

The operation of our machine is as fol- A supply of spool cores 24 arelaced in the hopper 18 and a supply of an es in hoppers 83. For "0hrpreferred is pe of spool, as shown in Fig. 41, we prefer to supply onehopper 83 with flanges 77 having 3 slots 7 9 and the other hopper 83with flanges 77 having-merely central apertures 81.

The cores 24 slide down chutes 26 and land in notches 17 of the mainrotor 1.

-Rotor 1 is then. adva iced 90 by v(irenevagear bringing the first coreto the flange applying and welding station, and at the same time asecond core 24-drops in a pair of notches 17.-

, Flanges 77 slide down from each hopper '83 and are weldedby electrodes79 to the core, and Geneva 10 again functions, so that the first spoolis-moved to the bottom of the rotor, the second core to the flangeapplying and welding position and a third core rolls onto rotor 1.

After the pads 192 strike the flanges to .size the spool for length,Geneva moves the rotor one step and the sized spool is brought to itstransfer position in which position it is grasped by the centering pins192 of the transfer rotor 2.

When rotor 2 is advanced by Geneva gear 9, the spool is brought to thespool tester 10 where the strength of the weld'is determined, and if abreak occurs the spool is discarded.

Another actuation of'Geneva 9 moves the spool, if a good one, to thesizing station 0 where, if of the correct size it is placed in Onereceptacle, and if too long is placed intoanother.

From the foregoin description it will be seen that we have pro duced amachine which will automatically turn out all metal film spools ofapredetermined length and strength.
